To all 'it Be it known that 1,1 Jmns F. PLAGE, a

citizen of the United States, and a resident n stances of any .kin

Aof olemidgeh lthe county of Essex und.

State of New erse have invented certain new and useful Improvements in Insulated l vContainers for LiquidfAir, &c., of lwhich the followi is a specification. y.

This'/lnvention' relates to vessels, bottles or receptacles, either portable or stationary,

for preservmg, carrying or storing liquid airy or other liquefiedv fgases, or liquids or subwhich it is desirable `to insulate from heat 'or cold; and may be 'considered' as an improvement on my inventions shown in- `I will now proceed to describe my-i'nven" .tion by help 'of the accompanying drawings, 1n which nected to the 'outer impervious inclosure in- Fi rell isa vertical section of an insulated vesse .as at present constructed :with some parte of my invention adapted thereto. 1g. 2 is a vertical section of the inner 'bottle f or container constructed in accordance with my present invention, the outer protecting case and reinforced insulation being omitted, said ligure showi a modification of Fig. 1, or the inner botte constructed and "conaccordance with my. present improvements. Fig'. 3 is a detail in elevation of ythe inner bottle of' Fi 1, showi the preferred constructionof oldi'ngt'oget er the heads. Fig. 4 is a plan viewonfthe line :c c of Fig. 1,

looking down on the top of theheadV f the outer case or receptacle, and showing the preferred manner of `lixi to the head of such outer case or receptac e the sus-pendi cords, ropes or rods from which is suspende the inner bottle. the outer caseor receptacle shown in 1, on the' line y vy of F1g.. 1, lookingupward, showing the preflerred'manner of iixm'g the stays,. 'y rods or laterall cords, which 'pres vent t e lateral movement of the inner bottle; These lateral cords or guy rods may be so arranged in double sets as shown in soldered,

as to'closev the Fig. 5 is across section of Figs. y1 mi2 o me su' "pen the inner boule from thes'd'e walls oft e outer case, as weil as to prevent -lateral movement of the saine.

Figs. 6 and 7 are vertical sectional views',

showing a modification in construction of the inner bottle, and dierent ways of suspending the same to the head of the outer case lor receptacle'. Fig.y 8 is .a mere detail of` the sus' `riding rod ,shown in Fig. 6.`

nnilar reference marks refer to similar parts throughout the several drawings. In Figs. land 2, the numeral 1 refers to the outer case or outer receptacle, within which is suspended the inner bottle, or insu'-v lated container 2. At 2is shown the neck y2; this is' in accordance with my invention covered by U. S. Patent 707,634, which-is shown here for the purpose of com arisen..

2 the inner bottle itsef (2) is:

But in F' lgrazed or iixed with an air-ti4 ht joint to the sack inclosure 4. This join is' shown at 6 (see Fig.,2) where the neck of. mouth (2 of the inner bottle is expanded' ypreferably into a flange 2, and which flange tlhtly connected with the sack-inclosurel he neck (2) of-,the inner bottle itself (and not the lining thereof) lis here connected` f with or fixed to the mouth of said sackl or inclosure 4, so as to leave the mouth or neck (2') 4of said bottle (2) o en, in which is in# sertedfrom the outside t e stopper 7 and so outh of said sack or outercase covering 4, Jand thus the twoitog'ethe'r l (the inner bottle 2 andthe sack or impervious covering 4) are made to form'one complete air-tight inclosure around said outer case 1. Thus at 8 (see Fig. 2) is provided a vacuum space, which vacuum is produced preferably by attaching a vacuum pump to the outlet of the check valvey 9. This form of construc-l tion of making the air-tight sheet metal inclosure (4) around the outer case and the in ner bottle (2) itself, one and the same complete inclosure (see Fig. 2), 1s an improve# ment on the construction shown in my U. S.' Patent 707,634, wherein theoutercase inclosure is combined with the lining of the inner bottle to form the one complete air-tight inclosure.

The inner bottle 2 when made substantially in accordance with my present invention or the construction shown in Fig. 2, 1s covered referably by the paper inclosure 10 and the air felt packing 11,' but this paper covering and this hair-felt packing are not essential, the vacuum 8 being depended on entirely to insula'te the bottle or suspended vessel 2 againstthe outside temperatures. The bottle may be made in two parts of any suitable material such as copper, brass or German silver, and screwed together as at the joint l2, and reinforced by soldering or brazing so as to make it erfectly air-tight.

When made substantially 1n accordance with my present invention, the heads (top and bottom)`of.the outer-case (l) are made of wood or some other similar material in several thin disks glued or otherwise closely held together, the grains crossed, as shown at 13, 13 and 13" or 14, 15, 16, 17 and 18 (see Figs. 1 and 2). At 19 in Figs. 1, 2 and 4 I show supporting cords, cab es, strands, rods or wires Which are preferably passed through the head 13 and 13 of the outer case, and

fixed to the top of this inner bottle as shown in Figs. 1, 2 and 4, and by which the inner bottle (2) is suspended within the vacuum space 8. These suspending cords may be in form of rods, as shown at 19a in Figs. 6 and 8, or of catgut or strong twisted fiber, such as silk, linen or hemp, as shown at 19 in Figs. 1, 2 and 4. At 19c (Fig. 7) a modification is 'shown in which the suspending rod is made of wood, the upper end being held in the'head 13 by the wedge 20. The heads (top and' bottom) of the inner. bottle, when constructed as shown in Fig. 1, are`made preferably of wood or fiber dlsks, as shown at 21 and 22; and the suspending cordsmay be fastened to hooks 23 and 23, or ma be attached to wood pins, as shown in Fig. 6; or the rods may have heads as shown in Fig. 7. i

When the inner bottle 2 is constructed substantially in accordance with my present invention, as shown in Fig. 2, the suspend' the outside of the bottle by t be attached to e eyes 26. Any other suitable manner of' attaching these suspending ropes, wires or rods to the top head of the outer case 1 and the inner'bottle 2, will answer; the preferred construction is to have the su ports fixedto the outer case head 13, underneath the sack inclosure 4 as shown in Fi s. 1 and 2, and to the inner bottle outside the lining5 in 1 or outside the shell of the inner bottle as in Fig. 2-being within or passing throu h the vacuum space 8.

At 27 1n Figs. 1 an 2 I show an annular projection, extending downwardly outside supports, cords or rods, mayl from the bottom of the inner bottle, and to this is attachedv the uy ro es or rods 28, which pass throu h t e wa s of the outer case 1 as shown in ig. 5, and are drawn taut so as to prevent any ateral movement of the inner bottle. These' lateral guys, rods or Wires may be of any suitable material, but are perferably of cat-gut, silk, linen, hemp or some other material of relativelylow heatconductivity;v and the sus ending vcords or rods 19 are preferably of similar material of relatively low heat-conductivity, so that in each case it will be more difficult for heatto' pass in to o`r out from the contents ofthe outer bottle 2.

At 29 (Figs. 1 and 2) I have guys similar alsol to support the inner bottle 2 in positionl within the vacuum space 8 in the outer case` 1.4 All of these guys, ropes or rods are 1ocatedvpreferably all within the 'vacuum space surrounded by or inclosed in the inclosure 4.,

I am aware that ininsulated receptacles of this class', cords of fiber and lateral stays have been used; but I make use of such in a new and novel manner so as to relieve the strain on the neck of the insulated container, and to virtually take and sustain full .the we' ht of the substance being insulatecf. In or er to prevent heat from passing through said neck, either in or out, and to properly insulate the contents of the container it is essential that the sectional area of the tube of the neck should be very small and the smaller it is the less wei ht it will carry. If the neck is made,

of suflic1ent thickness of shell to sustain alone the wei ht of the substance being insulated, the insu ation will be imperfect and unsatisfactory.

VWhen the inner bottle is made with a lining as shown in Fig. 1, I prefer that the heads 21.and 22 (top and bottom) should be held together b an endless cord or wire as shown at 30 in 3, which'is d rawn taut, ve similar to t e well known manner in Whic the heads of a drum are held to the cylinder thereof. In this way metal screws or Inaterials which conduct heat are avoided.

The outer case 1 is preferably inclosed by hair-felt packings 31 (see Fig. 1) and the out? -,a'cover 33;v

side protecti case 32, ha

the inner botltle being providierdgwith a pa er or glass siphon tube 34, g'age 35, safety va ve 36 and discharge cock 37, when such bottle is used for holding or preserving li uid air or other liquid gases connecting wit the discharge pipe 38. At 39 (Fig. 1) I have a removable dischar e tube, of suitable non-conducting materia which incloses the mouth side of the case 32, so that any vapor that escapes from the inner liuid-holding' bottle 2, passes down through t e insulating pack of the safety valve 36, and delivers to the in- A ings 31, and out through the hole in thel bottom of the case 31thus serving to insulate the case 1 from heat and keep it cool.

Having thus described my invention what I claim as new and original and desire to 4 secure by Letters Patent, is

1. A vessel for holding and preserving liquid air or other liquid gases, comprising in operative combination, an outer rigid case of Wood or other material of relatively low thermal conductivity, inclosing a vacuum space; an impervious air-tight sheet metal ,envelop around said outer case; l and an inner bottle made. of impervious sheet metal suspended from said outer case within said vacuum s ace by non-conducting cords of silk or ot erv fibrous -material, said bottle havin a long neck Whichis soldered or braz'e to said' air-tight envelop around said outer case-said envelop and said neck and bottle forming one complete air-tight in` closure, which incloses said outer case and the vacuum space therein.

2. A container for holding liquid air or other substances and insulating the same against the normal heat of its environments, comprisin in operative combination an outer rigi case having or surrounding therevessel within the vacuum space in said outer case, having a long tubular neck soldered or brazed air-tight to said implervious inclosure-said inner vessel being ung from said outer case by a plurality of pendent sup- .ports of ber or other materia mal conductivity inside of said impervious inclosure. 3. A containerfor holding liquid'air, or other substances and insulating the same against the normal heat of its environments,

comprising in operative combination' an outer rigi case of Wood or other material of relatively low thermal conductivity, having of low ther,

or surrounding therein a vacuum space; van

impervious sheet metal envelop around or inclosing said outer case; a-n inner insulating vessel Within the vacuum space in said outer case, having a tubular neck connected or joined air-tight to said impervious'envelop, said inner vessel being hung from said outer case by a plurality of pendent supports of fiber or other material of low thermal conductivity, and forming with said tubular neck and said sheet-metal envelop one complete air-tight inclosure around said outer case and the vacuum space therein; and guys or lateral stays of low thermal conductivity fixed radially to said inner insulating vessel and to the walls of said outer ri id case.

4. A container for holding 'quid air or other substancesand insulating the same against circumambient temperatures, comrising in operative combination an outer rigid case of Wood or other material of relatively loW thermal conductivity, having or surrounding therein a vacuum space; an impervious envelop around or inclosing said outer case; an inner insulating vessel within the vacuum space in said outer case, having a tubular nec to said impervious envelop-said inner vessel bein hung from said outer case by a plurality o pen ent supports of fiber or other material of relatively low thermal conductivity,' and forming with said tubular neck, and said impervious envelop one complete' connected or joined air-tight A York and State of New York this 13th day 85 of June A.
